BOLSTER.

SPECIFICATION 'forming part of Letters Patent Nog'rsvuee, dated August 25, 1,903.

i Application led April 23,1903.`

To all whom, it may concern/:

Be it known that I, WILLIAM Hl Soorr, a citizen of the United States, residing vat St. Louis, Missouri, have invented a certain new and useful Improvement in Bolsters, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this Figure 1 is a top plan view, partly broken away, illustrating my invention. Fig. 2 is a side elevationalv view, partly broken away. Fig. 3 is an isometric perspective view showing the several parts of the head-block with compression and tension members. Fig.,4

is a sectional view on the line`4 4 of Fig. 2.

Fig. 5 is a plan'view of a modified form of head-block. Fig. 6 isaside elevational view of Fig. 5. Fig. 7 is aside elevational view, partly broken away, illustrating a modified form of head-block. Figs. 8, 9,10, and-11 are detail views illustrating vmodified forms of the enlarged end of the tension member of my bolster; and Fig. 12 is a view in section, illustrating the manner of tying the several parts of my bolster together without the use of tie-bolts as shown in the other. views.

This invention relates, broadly, to new and useful improvements in trussed holsters, wherein the head-block is separable laterally for the purpose of permitting the introdu'c-v tion therein of the ends of a tension member: which is held in seats 'in said'head-blocks, and consists, in addition thereto, of certain features of detail construction and arrange-A ment of parts, all as hereinafter more fully-V described, and particularly pointed out-in the claims.

Referring to the drawings, 1 is a compression member, which is preferably of channel l form in cross-section and may be vmade of a commercially-rolled channel. f f 2 is a tension member, which may be forme from a iiat plate, as shown in the drawings, with the end portions thereof provided with .any method or style of enlargement which will adapt it to coperate with the separable headblock sections hereinafter described and be held by said head-block sections in position. In views 1 and 2 the tension member consein No. 153,996. ons model.)

end, upon ythe end portions ot' which areY welded the stub sections 3, which in those kviews are. formed wider than the plate 2, whereby 'laterally-extending shoulders 4 are provided, adapted to interlock with inwardlyprojecting shoulders 5, formed in the headblock sections. y

-In Fig. 8 the tension-member is provided with a returned lbentportion 4, flattened upon the tension member 2. Y In Figui) the metal of the tension lmember is thickened by any convenient process, as shown at 4b, 4to provide .a shoulder above and below the-plate 2.

In Fig. 10 the metal is formed with acentralopeningextendinglaterallytherethrough, a shoulder 4c being provided above and below the'plate 2.

In Fig. 11 the enlarged Y 2 embraces alaterally-extendingl rod 6 which provides additional supporting means for the tension member, adapted to 'interlock with correspondingrecesses inthehead-block sections.

The form ot the end portion of the tension vmember'is immaterial, and it may, if 'necessary, be merely a fiat plate, as shown in Fig.

7, which is provided with rivet-openings Ythrough which the rivet 7 is projected to secure the plate 2 within the head-block sec tions.

The essential vfeatu re of novelty in the present bolster resides in the fact that the headlblock sections are separable laterally forjthe purpose ot` taking in the ends of the tension member and when restored to their normal operative position lock therein the ends of the tension member, the head-blocks' being provided either with channelrecesses vv8,7 as best shown in Fig. 3, for the flanges 9 of the channel 1 orwith a laterally-projected opening through which may be extended a bolt, as`10, for tying the several parts of the-.headblock together. v

In the drawings at Fig. 3 the several headend 4l of the plate I block sections are shown asseparate'ly-formed .seats extend laterally thereof for the purpose ot holding the enlarged ends ot' the tension member 2, while beneath the head-block secrco tions 12 is a spring-plate 13, provided withupwardly-extended llanges 14, which flanges em brace the annular recess 15, formed at the lower edges of the blocks 12, whereby said blocks 12 are held against lateral separation, though the column-guides 16, cooperating with the columns commonly incident to railway-trucks, would hold the parts of the headblock in operative position under normal con Io ditions without the use of the spring-plate 13.

In the modification shown at Figs. 5 and 6 flanges 17 are provided beyond the ends of the head-block sections, through which may ploject suitable rivets 1S for securely lock- I5 ing the head-block sections together, while corresponding flanges 17a on the inner side of the head-blocks below the tension member2 are also provided as additional securing means through which rivets may project, if desired.

zo Thus it will be seen that by means of the head-block sections and the locking means provided it is possible to use an imperforate tension member and an imperforate compression member, or either, if desired, and in practical use no means are required to hold the parts of the bolster together, except such as are incidental to the construction of the several parts thereof. For convenience in shipping, however, bolts, such as 10, or rivets, as

3o 18, are used to unite the several parts of the head-block sections and hold them against lateral separation. It will be observed that the holsters illustrated in the drawings may be provided with spring-seats 13 or without such spring-seats where the head-block sections are held together by any means foreign thereto-as, for instance, the flanges 9 of the channel compression member. The springseats 13, with their upwardly projecting 4o flanges, are non-essential, and the same would be true if the compression member were reversed so that the llanges would project upwardly, provided some means, like the flanges 17 and 17, were provided through which securing means could be passed to hold the parts in operative position.

In addition to the features heretofore enumerated I use with my improved bolster the tie-plates 19, which are secured to the ilanges 5o 9 of the compression member by suitable rivets and extend thence downwardly below the tension member. The said tie-plates 19 are secured to the compression member at approximately the point where the side bearings are usually placed, and the object of the tie-plates 19 is to prevent buckling of the cambered compression member 1, as it has been found that under some extraordinary conditions the said compression member has a 6o slight tendency to buckle, which would of course destroy the efficiency thereof.

- For convenience in shipping the screws 20 are used to secure the spring-plate in position below the head-block sections, though it will .be apparent that such securing means are not required in actual service.

I am aware that minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.
